摘要
本研究使用碱性乙醇为溶解试剂对聚酯纤维与某些其他纤维混纺产品进行定量分析,在 70℃水浴中振荡溶解15 min,将聚酯纤维从已知干燥质量的混合物中溶解去除,将残留物清洗、烘干和称重,从而计算出各组分纤维的质量百分含量.GB/T 2910.24-2009《纺织品 定量化学分析 第24部分:聚酯纤维与某些其他纤维的混合物(苯酚/四氯乙烷法)》中使用的试剂是苯酚/四氯乙烷,具有一定毒性,对环境和人体健康有一定影响,对实验环境和废液回收有较高要求.使用碱性乙醇法可以降低对环境的污染和身体健康的危害,且该方法操作简单、准确可靠,适用于聚酯纤维与某些其他纤维混纺的定量分析.
Abstract
This article employs alkaline ethanol as a dissolving agent to quantitatively analyze polyester fibers and certain other fiber blended products.The analysis involves oscillating and dissolving the mixure in a 70℃water bath for 15 minutes,extracting polyster fibers from the known dry mass.The residue is then washed,dried,and weighed to calculate the mass percentage content of each component fiber.The national standard GB/T 2910.24-2009 Textiles-Quantitative Chemical Analysis-Part 24:Mixtures of Polyester and Certain Other Fibers(phenol/tetrachloroethane method)utilizes phenol/tetrachloroethane as the reagent.However,this reagent,possesses certain toxicity,has adverse effects on environment and human health and requires strict conditions for experimental environment and waste liquid recovery.In contrast,the alkaline ethanol method provides a more environmentally friendly and health-conscious alternative.With simple,accurate,and reliable procedures,it is well-suited for the quantitative analysis of polyester fibers mixed with certain other fibers.
